There are many reasons for this. Here are some possible explanations: 1. Pressure: There may be a lot of pressure in life, such as work, study, family, etc. If these pressures were not dealt with properly, it could lead to emotional instability and violent behavior. Mental health problems: If there are mental health problems such as depression, anxiety, etc., it may also lead to emotional instability and violent behavior. 3. Drug or alcohol use: Drug or alcohol abuse may affect brain function, resulting in emotional instability and even violent behavior. Past experiences: Past experiences such as violence, abuse, sexual assault, etc. may affect emotions and lead to violent behavior. 5. Self-control: People with insufficient self-control may have difficulty controlling their emotions and are prone to violent behavior. If this happens, it is recommended to seek professional psychological consultation or treatment to help you solve your emotional problems. At the same time, you also need to pay attention to your physical and mental health, maintain good living habits, participate in physical exercise, social activities, etc. to enhance your physical and mental health.
